Other news outlets reported that the man carrying out the assault was named Yasir El-off.

It was in July 2011 when Free Syrian Army was formulated as one of the first factions in the expansion of the Syrian Civil War. It was established by Syrian Armed Forces, who gave away the allegiance for Syrian dictator Bashar al-Assad. Their motto and mission shifted to bring down Assad and his regime.

However, the faction gradually took a jihadist stance. Since 2016, the Free Syrian Army stopped being an organized faction. In contrary, it turned into a promotional label, which militia groups in the Syrian Civil War randomly use or reject.

The Sham Legion or Faylaq Al-Sham is one group utilizing the Free Syrian Army name. The faction acted as one the Islam rebel groups whose mission was to establish a moderate Islamist point of view.

U.S. has been consistently supporting these groups in the fight against the Islamic State.

Syria News: Free Syrian Army Threatens US

The city of Aleppo was captured weeks ago from the Islamic State by the Free Syrian Army. The win came after they were aided by Turkish troops and U.S. air power.

However, a disturbing video has been released showing U.S.-backed Free Syrian Army (FSA) rebels threatening to kill arriving U.S. special operations forces in the town of Al-Rai near Aleppo.

“Death to America! We will behead you!” members of the FSA shouted in the video.

“Christians and Americans have no place among us,” one man shouted in the video.

“They want to wage a crusader war to occupy Syria.”

According to PJ Media, the members of the FSA shouted anti-American slogans while a convoy of pick-up trucks carrying U.S. commandos drove away from them.
